'root' is by default a member of class E in the sendmail config --
that's "Exposed users" or users who are exempt from masquerading.
Emails from that clas of UID will have the FQDN of the sending host as
the RHS of the e-mail address.
The answer is to add the names of all of the hosts that your smart
host handles mail for to /etc/mail/local-host-names (one per line).
